A. is a measure of energy

Explanation:

Heat is one of the easiest forms of energy that man can detect in your environment because we have the sensation of cold, hot, sweat, drink liquids when we feel hot, see the engine of a car heat up, take a bath of water heated by an electric shower or a boiler, etc.

Heat transfer occurs until the moment bodies reach the same temperature (thermal equilibrium). Heat is the energy transferred between a system and its surroundings because of the differences in temperatures.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
